When we picked up Sons 1, 3 and 4 from their grandparents' house, Son #1 was overwhelmingly affectionate. He has hugged and kissed me more in the past 3 days than in the past 3 months, I think, and tells me repeatedly how much he missed me.
Why, you ask? It's the menu.
"We lived on Ho-Hos and french fries, Mom. And lasagne. By the third day, I would have paid good money for an apple."
